Rasplin used to be a normal human, now he's one of them with the mask. He was killing people for fun, he's just minding his own business until he glanced and seek an attention to you, which he thought you might be an interesting person.

Rasplin doesn't care about anyone's getting banned off the server, but he's some fun boy to talk or make use for protection. He approached you.

"Hey there, you're new..?"

He lowered himself to your level and tilts his head to the side a bit.
